Other members about Jungkook:
- Suga: "Jungkook has a good memory so he can imitate us well. And I remember that when Jungkook first came, he was shorter than me. Seeing him grow taller makes me feel like I've raised him."
- Jimin: "I'm 2 years older than him but he keeps making fun of me for my height."
- Jin: "He's quite bad at refusing requests."
- Rap Monster: "Individualistic, doesn't share clothes. Washes his clothes separately. A slight timid-ness that's like a maknae. Although he wants to seem manly, he's actually a cutie. Although his passion overflows, it doesn't go on long. Puberty, rebellious, but it seems cute."
- J-Hope: "He's the maknae who talks backs a lot and doesn't listen. Although he personality is quite kind... I also have no answer for his personality"
- V: "Truthfully, he's the same as me. I have no answer."
- Suga: "Because he's the youngest, he's still immature. However, he clearly shows what he likes and what he dislikes."
- Jimin: "He's kind, innocent, and is bad at expressing his feelings. That's why he's cute. Jeonggukkie's mine
